Can anyone tell me what does the abs () function do?

Answer 1

People above me already answered you , but I'm gonna define what the absolute really means - It's the distance from 0 to the number you want . For example , the absolute value of -500 means what's the distance between 0 and -500 ? The distance can't be negative number because you don't say -5 meters. Think of it as a line of numbers and in center of that line you have 0 , the distance between 0 and any number you pick on that line will be the positive value of that number. So absolute value of -5 is 5 , absolute value of 263 is 263 and so on . Hope I helped you :)
